使用apt-mirror搭建debian镜像源-剩余价值

使用apt-mirror搭建debian镜像源

debian官方提供了脚本ftpsync来搭建源镜像，而 apt-mirror 是一个更简单便捷的源镜像搭建工具。

安装 apt-mirror

sudo apt-get install apt-mirror

配置文件/etc/apt/mirror.list只要修改很少的地方，大部分使用默认值即可。

这里使用中科大镜像 ftp.cn.debian.org 作为上游镜像，只镜像 debian jessie amd64 架构，不镜像源代码包。

############# config ##################
#
# set base_path    /var/spool/apt-mirror
#
# set mirror_path  $base_path/mirror
# set skel_path    $base_path/skel
# set var_path     $base_path/var
# set cleanscript $var_path/clean.sh
# set defaultarch  　# 默认架构与镜像主机的架构一致,这里是amd64
# set postmirror_script $var_path/postmirror.sh
# set run_postmirror 0
set nthreads     20
set _tilde 0
#
############# end config ##############

开启自动同步

只需 root 权限 cron 自动运行 apt-mirror 命令即可。

# vim /etc/cron.d/apt-mirror

0 0 * * * apt-mirror > /var/spool/apt-mirror/var/cron.log 2>&1

或者crontab -e

# m h  dom mon dow   command
0 0 * * * apt-mirror

发布镜像服务

使用nginx发布源镜像

将 apt-mirror 的镜像目录链接到/var/www/mirror

# ln -sf /var/spool/apt-mirror/mirror/ftp.cn.debian.org/ mirror

然后将nginx默认主机default(或者单独虚拟主机)的根目录设置为/var/www/mirror,并开启目录列表

root /var/www/mirror
location / {
    autoindex on;
}

其他机器就可以正常使用新建的源镜像了。

另：

apt-mirror能够将官方镜像下载到本地，并保证目录结构与其一致，但是不能对镜像仓库进行修改。如果想要修改镜像仓库，需要使用reprepro。

1、安装apt-mirror

# aptitude update
# aptitude install -y apt-mirror

# dpkg -L apt-mirror
/.
/usr
/usr/bin
/usr/bin/apt-mirror
/usr/share
/usr/share/man
/usr/share/man/man1
/usr/share/man/man1/apt-mirror.1.gz
/usr/share/doc
/usr/share/doc/apt-mirror
/usr/share/doc/apt-mirror/changelog.gz
/usr/share/doc/apt-mirror/changelog.Debian.gz
/usr/share/doc/apt-mirror/copyright
/etc
/etc/cron.d
/etc/cron.d/apt-mirror
/etc/apt
/etc/apt/mirror.list
/var
/var/spool
/var/spool/apt-mirror
/var/spool/apt-mirror/skel
/var/spool/apt-mirror/mirror
/var/spool/apt-mirror/var

2、修改配置文件，添加要下载的源（我这里添加的是debian_squeeze的源）

# vim /etc/apt/mirror.list

set base_path    /docker/debian_mirror
set mirror_path  $base_path/mirror
set skel_path    $base_path/skel
set var_path     $base_path/var
set cleanscript $var_path/clean.sh
set defaultarch  <running host architecture>
set postmirror_script $var_path/postmirror.sh
set run_postmirror 0
set nthreads     40
set _tilde 0

deb-amd64 http://archive.debian.org/debian squeeze main
deb-amd64 http://archive.debian.org/debian squeeze-lts main

3、手动运行apt-mirror下载镜像

# apt-mirror

0 bytes in 0 files and 0 directories can be freed.
Run /docker/debian_mirror/var/clean.sh for this purpose.

4、设置定时任务，定时与官方源同步

# vim /etc/cron.d/apt-mirror
0 0 * * * apt-mirror > /docker/mirror.log 2>&1

5、设置发布目录软链接

# ln -sv /docker/debian_mirror/mirror/archive.debian.org /docker/mirror

6、配置nginx发布镜像目录

# cd /usr/local/nginx/conf/vhosts/
# vim debian_mirror.conf

server {
    listen 8081;
    server_name debian_mirror;

    root /docker/mirror
    location / {
        autoindex on;
    }

    access_log /usr/local/nginx/logs/debian_mirror.access.log oupeng_logs;
    error_log /usr/local/nginx/logs/debian_mirror.error.log;
}

# /usr/local/nginx/sbin/nginx -t
# /usr/local/nginx/sbin/nginx -s reload

7、找一台debian6的机器添加本地源测试

# vim /etc/apt/sources.list
deb http://117.119.33.138:8081/debian squeeze main
deb http://117.119.33.138:8081/debian squeeze-lts main

# aptitude update
Hit http://117.119.33.138 squeeze Release.gpg
Ign http://117.119.33.138/debian/ squeeze/main Translation-en
Ign http://117.119.33.138/debian/ squeeze/main Translation-en_US

Ign http://117.119.33.138/debian/ squeeze-lts/main Translation-en

E: Release file expired, ignoring http://117.119.33.138:8081/debian/dists/squeeze-lts/Release (invalid since 524d 12h 54min 42s)

其中第二个源squeeze-lts会提示过期，在apt配置文件中添加一项配置即可

# vim /etc/apt/apt.conf
Acquire::Check-Valid-Until false;

# aptitude update
